Answer: x=58+57=115

y=178-115=63


Step-by-step explanation:

Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.

Then, x= Grade 3 computers +Grade 4 computers.

\Rightarrow\ x=58+57=115

And y = Total computers - x

\Rightarrow\ y=178-115=63

Therefore, The  equations can be used to find how many computers the rest of the school has.

x=58+57=115

y=178-115=63

lilavasa [31]

Answer:

Method A.

Step-by-step explanation:

For solving this question we need to find out the z-scores for both methods,

Since, the z-score formula is,

z=\frac{x-\mu}{\sigma}

Where, \mu is mean,

\sigma is standard deviation,

Given,

For method A,

\mu = 33

\sigma=8

Thus, the z score for 34 is,

z_1=\frac{34-33}{8}=0.125

While, for method B,

\mu = 37

\sigma = 4

Thus, the z score for 34 is,

z_2=\frac{34-37}{4}=-0.75,

Since, z_1 > z_2

Hence, method A is preferred if the procedure must be completed within 34 minutes.

The coordinates of the mid-point between points B and C is given by:

(-5, -10).

<h3>What is the mid-point concept?</h3>

The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.

The points in this problem are given as follows:

B(-40, -30), C(30, 10)

Hence the coordinates of the mid-point are:

  • x = (-40 + 30)/2 = -5.
  • y = (-30 + 10)/2 = -10.
